Even though people can have same pleasure from sex, the anatomy still differs pretty much if we consider all features of men and women. This is why Colt XL Big Boy is specially designed for male use. First of all, the space in male rectum is way bigger than ladies have. Plugs should be much larger to give fulfilling sensations, yet anal ring needs more care as it’s less stretchy than female. Big Boy is made of plushy safe silicone with tapered tip for smooth insertion and great sensations inside. The narrow zone for ring hug when fully inside is slimmer than in any female plug to keep your anus safe. Before use, massage your anal hole with circular moves and stretch it with fingers. Hot bath or other relaxation will help. Insert the plug with careful screwing moves having added plenty of water based lube. 4.5 to 3 inches size for maximum male stretch.
